Abstract:
· AIM: To study the in situ relative intraocular position of the iris-claw phakic intraocular lens (PIOL)for high myopia using an anterior chamber optical coherence tomography (AC OCT)prototype.· METHODS: Six PIOLs (11.50 to 22.00D lens powers) were implanted in phakic myopic eyes. Using AC OCT, tomography was taken in the anterior chamber to measure the preoperative anterior chamber depth, postoperative distance between the PIOL and the corneal endothelium (endothelial-optic distance), and the postoperative distance between the PIOL and the crystalline lens.· RESULTS: Preoperative anterior chamber depth ranged from 3.27 to 3.91 mm and the postoperative endothelial-optic distance measured 2,07 to 2,24 mm. The distance between the crystalline lens and the posterior surface of the IOL ranged from 0.82 to 1.32 mm. Several tomography revealed the position of the PIOL on the iris, The pigment layer of the iris did not seem to be disturbed by the presence of the PIOL.· CONCLUSION, The original anterior chamber depths were reduced by 36,1% to 44.6% after implantation. This study of 6 eyes revealed that tomography taken by AC OCT are useful in verifying the intraocular position of the PIOL within the anterior chamber. Adequate space was maintained between the iris-fixated phakic intraocular lens and the corneal endothelium, angle, and crystalline lens.
